1 . A compressing device, the device comprising a receptacle for holding items to be compressed and compressing means for compressing items within the receptacle, the compressing means comprising a compressing member and an arm coupled thereto, the compressing means further comprising a worm drive for driving the arm between an extended configuration in which the compressing member extends within the receptacle and a retracted configuration, in which the compressing member is removed from the receptacle.

2. A compressing device according to claim 1 , wherein the arm comprises a proximal end that is coupled to the worm drive and a distal end that is coupled to the compressing member.

3. A compressing device according to claim 2, wherein the separation of the proximal end of the arm from the receptacle is fixed so that the arm can develop a compressive force on items within the receptacle, when arranged in an extended configuration.

4. A compressing device according to any preceding claim, wherein the worm drive comprises a worm gear disposed upon a drive shaft, which is arranged to engage with a worm wheel disposed upon a threaded shaft.

5. A compressing device according to claim 4 as appended to claim 2 or 3, wherein the proximal end of the arm is arranged in threaded cooperation with the threaded shaft and the distal end of the arm is slidably coupled to the compressing member.

9. A compressing device according to claim 7 and 8, wherein a distal end of the first pair of levers is hingedly coupled to the proximal end of the second pair of levers.

10. A compressing device according to any of claims 6 to 9, wherein the lever arrangement comprises a lazy tongs type arrangement.

1 1 . A compressing device according to any preceding claim, wherein the worm gear is driven by a motor.

12. A compressing device according to any preceding claim, wherein the compressing means and receptacle are housed within a housing.

13. A compressing device according to claim 12, wherein the receptacle is removably positionable within the housing.
